Good, well thought out work.
But we can do without the "Grid_ColPos2Ind" function. Not critical for a small number of columns.

And an interesting take on the solution from Derek.

Hi Roberto, Konstantin,
Attached are a couple of suggestions that might help.
1.  Hide Columns Persistent.
With this option, the selection of hidden columns is persistent between sessions. 
Click on the 'Columns' button and then click on the columns in the 'pop-up' grid that you want to hide / unhide (highlighted with an 'x') and then click on the 'Columns' button again.
2.  Re-sort Columns Persistent.
With this option, the order of the columns in the tablegrid is persistent between sessions.
Click on the 'Columns' button and then 'drag and drop' the columns in the 'pop-up' grid in whatever order you want.  When they are in the order that you want, click on the 'Columns' button again to re-sort the tablegrid.
Maybe this can give you some ideas.
Regards,
Derek.

Hi Derek, I understand the dynamics of storing information about modified columns in a specific table and restoring this situation in the OnShow procedure. Thank you.

Custom column settings: built-in capabilities supplemented by scripts.

Very good, congratulations!

Is the current user setting for visibility and column position saved the next time the application is launched?

Hi k245! I ran some tests with an application without any scripts, and unfortunately, the information about which columns were hidden or moved isn't saved.

Anyway, my goal was to enable better analysis of monthly values by comparing specific columns and moving and/or hiding one or more of them.

To do this, in the tablegrid properties, options, set the properties to the following status:
- goCanHideColumn = true
- goDisableColumnMoving = false
